This depends on if what you are feeling is an open margin (which is a gap between the tooth and the crown) or overhang (which is they made the crown a little too thick and it hangs over the edge of the tooth a little). If it is an open margin then bacteria can get in. If it is overhang, then it may still be sealed and free from bacteria. either way, I'd go back to the dentist and get it checked out.

Should I Feel The Edge Of My Crown?
Feeling edge of Crown
You should not be able to feel the edge of your new crown. I would call your doctor to make an appointment to have that corrected.
